2003-01-02BIG patch...Andrew Bartlett1-2/+2
This patch makes Samba compile cleanly with -Wwrite-strings. - That is, all string literals are marked as 'const'. These strings are always read only, this just marks them as such for passing to other functions. What is most supprising is that I didn't need to change more than a few lines of code (all in 'net', which got a small cleanup of net.h and extern variables). The rest is just adding a lot of 'const'. As far as I can tell, I have not added any new warnings - apart from making all of tdbutil.c's function const (so they warn for adding that const string to struct).

2002-11-07when doing a 'net rpc vampire' a pdb_init_sam_pw() is used to create aAndrew Tridgell1-0/+3
sam account object, then pdb_update_sam_account() can be used to update an account. This code path could lead to the methods element of the account being used when uninitialised (leading to a segv) Easiest fix is to always make that that when creating a sam_account object we initialise the methods to null, so that the passdb code knows that it needs to be filled in.

2002-10-21This moves the group mapping API into the passdb backend.Volker Lendecke1-7/+7
Currently this calls back to mapping.c, but we have the framework to get the information into LDAP and the passdb.tdb (should we? I think so..). This has received moderate testing with net rpc vampire and usrmgr. I found the add_groupmem segfault in add_aliasmem as well, but that will be another checkin.

2002-10-12Nice *big* patch from metze.Andrew Bartlett1-28/+27
The actual design change is relitivly small however: It all goes back to jerry's 'BOOL store', added to many of the elements in a SAM_ACCOUNT. This ensured that smb.conf defaults did not get 'fixed' into ldap. This was a great win for admins, and this patch follows in the same way. This patch extends the concept - we don't store values back into LDAP unless they have been changed. So if we read a value, but don't update it, or we read a value, find it's not there and use a default, we will not update ldap with that value. This reduced clutter in our LDAP DB, and makes it easier to change defaults later on. Metze's particular problem was that when we 'write back' an unchanged value, we would clear any muliple values in that feild. Now he can still have his mulitivalued 'uid' feild, without Samba changing it for *every* other operation. This also applies to many other attributes, and helps to eliminate a nasty race condition. (Time between get and set) This patch is big, and needs more testing, but metze has tested usrmgr, and I've fixed some pdbedit bugs, and tested domain joins, so it isn't compleatly flawed ;-). The same system will be introduced into the SAM code shortly, but this fixes bugs that people were coming across in production uses of Samba 3.0/HEAD, hence it's inclusion here.

2002-09-26Patch from "Stefan (metze) Metzmacher" <metze@metzemix.de> to do a *much*Andrew Bartlett1-1/+1
better job of working with usrmgr. Previously we were blanking out entires, and all sort of mischif. The new patch (which I've now had a chance to test/modify) also takes care not to expand % values (ie we go \\%L\%U -> \\server\user, we don't want to store \\server\user back) and to correctly notice 'not set' compared to 'null string' etc. Andrew Bartlett (This used to be commit ab878b6cc4132594fc33f78aeebf0d8b7266c150)

2002-09-25This patch from "Stefan (metze) Metzmacher" <metze@metzemix.de> cleans upAndrew Bartlett1-1/+10
pdb_ldap and adds a 'ldap passwd sync' option. The idea with this option is to do allow an ldap backend to do all the fancy password hashing etc - and to tell smbd no to try and double-up. Using 'ldap passwd sync = only' will do this, but is not recommended unless such a backend is in place... Running 'ldap passwd sync = yes' just gets you the same as doing 'pam passwd sync = yes' and having both PAM and pam_ldap correctly configured for 'magic root' behaviour, but only using ldap connection, and one set of credentials. This also gets us closer to allowing ldap to say 'password too short' etc, which might assist in maintaining a consistant password policy.

2002-08-17Rework the 'guest account get's RID 501' code again...Andrew Bartlett1-39/+37
This moves it right into the passdb subsystem, where we can do this in just one (or 2) places. Due to the fact that this code can be in a tight loop, I've had to make 'guest account' a 'const' paramater, where % macros cannot be used. In any case, if the 'guest account' varies, we are in for some nasty cases in the other code, so it's useful anyway. Andrew Bartlett (This used to be commit 8718e5e7b2651edad15f52a4262dc745df7ad70f)

2002-07-30Update a pile of Samba's SID lookup code to ensure:Andrew Bartlett1-40/+53
- That we never call winbind recursivly - That we never use an 'algorithmic' RID when we have a fixed uid or gid mapping in either the passdb or the group mapping db. Also, remove restrictions that say 'this domain only'. If we have a mapping configured, allow it to be returned. If we later decide certian mappings are invalid, then we sould put that in the code that actually does the map. Allow 'sid->name' transtations on the fixed 'well known' groups for NT, even if they are not represented by Unix groups yet.

2002-07-03Break up the passdb objects (to allow RPC clients to link without brining inAndrew Bartlett1-116/+0
*.o) and implment new enum_dom_users code in the SAMR RPC subsystem. Incresingly, we are using the pdb_get_{user,group}_sid() functions, in the eventual hope that we might one day support muliple domains off a single passdb. To extract the RID, we use sid_peek_check_rid(), and supply an 'expected' domain SID. The id21 -> SAM_ACCOUNT and id23 -> SAM_ACCOUNT code has been moved to srv_samr_util.c, to ease linking in passdb users. Compatiblity code that uses 'get_global_sam_sid()' for the 'expected' sid is in pdb_compat.c Andrew Bartlett (This used to be commit 5a2a6f1ba316489d118a8bdd9551b155226de94f)

rather than a string when configuring mulitple backends.

to using SIDs instead of RIDs. The new funciton sid_peek_check_rid() takes an 'expected domain sid' argument.

passdb interface change, now the passdb modules will be asked for SID not for rid, the modules have been updated with a passthrough function that calls the old getsampwrid() functions. srv_samr_nt.c functions that made use of the pdb_getsampwrid funcion has been updated to use the SID one.

2002-05-18A few things in this commit:Andrew Bartlett1-141/+169
cleanup some of the code in net_rpc_join re const warnings and fstrings. Passdb: Make the %u and %U substituions in passdb work. This is done by declaring these paramters to be 'const' and doing the substitution manually. I'm told this is us going full circle, but I can't really see a better way. Finally these things actually seem to work properly... Make the lanman code use the pdb's recorded values for homedir etc rather than the values from lp_*() Add code to set the plaintext password in the passdb, where it can decide how to store/set it. For use with a future 'ldap password change' option, or somthing like that... Add pdb_unix, so as to remove the 'not in passdb' special cases from the local_lookup_*() code. Quite small, as it uses the new 'struct passwd -> SAM_ACCOUNT' code that is now in just one place. (also used by pdb_smbpasswd) Other: Fix up the adding of [homes] at session setup time to actually pass the right string, that is the unix homedir, not the UNC path. Fix up [homes] so that for winbind users is picks the correct name. (bad interactions with the default domain code previously) Change the rpc_server/srv_lsa_nt.c code to match NT when for the SATUS_NONE_MAPPED reply: This was only being triggered on no queries, now it is on the 'no mappings' (ie all mappings failed). Checked against Win2k. Policy Question: Should SID -> unix_user.234/unix_group.364 be considered a mapping or not? Currently it isn't. Andrew Bartlett (This used to be commit c28668068b5a3b3cf3c4317e5fb32ec9957f3e34)
2002-04-13Better handling of uid/gid -> RID and RID -> uid/gid code.Andrew Bartlett1-21/+23
All uids and gids must create valid RIDs, becouse other code expects this, and can't handle the failure case. (ACL code in particular) Allow admins to adjust the base of the RID algorithm, so avoid clashes with users brought in from NT (for example). Put all the algorithm code back in one place, so that this change is global. Better coping with NULL sid pointers - but it still breaks a lot of stuff. BONUS: manpage entry for new paramater :-) counter based rids for normal users in tdbsam is disabled for the timebeing, idra and I will work out some things here soon I hope. Andrew Bartlett (This used to be commit 5275c94cdf0c64f347d4282f47088d084b1a7ea5)
2002-04-11Much better support for both non-algorithic RIDs (where the RID is stored inAndrew Bartlett1-135/+130
the passdb) and RIDs not in the passdb, due to being NIS users etc. The main fix here is to add become_root()/unbecome_root() at critical places. This (finally) fixes the bug where you could not see local users's names in a file's security properties as non-root. Tested. The similar bug in uid_to_sid is also fixed, but is not (yet) Tested.

2002-03-02This patch merges my private LDAP tree into HEAD.Andrew Bartlett1-10/+12
The main change here is to move ldap into the new pluggable passdb subsystem and to take the LDAP location as a 'location' paramter on the 'passdb backend' line in the smb.conf. This is an LDAP URL, parsed by OpenLDAP where supported, and by hand where it isn't. It also adds the ldap user suffix and ldap machine suffix smb.conf options, so that machines added to the LDAP dir don't get mixed in with people. Non-unix account support is also added. This means that machines don't need to be in /etc/passwd or in nss_ldap's scope. This code has stood up well under my production environment, so it relitivly well tested. I'm commiting this now becouse others have shown interest in using it, and there is no point 'hording' the code :-). Andrew Bartlett (This used to be commit cd5234d7dd7309d88944b83d807c1f1c2ca0460a)

2002-01-26 - Provide sid->name lookup support for non-unix accounts.Andrew Bartlett1-13/+39
- Rework the name -> sid lookup function to always try local lookup first (for local domain names) before trying winbind. This seems to eliminate my winbind feedback loop problems. (I don't use winbind for nsswitch, where there are almost certainly further issues). Andrew Bartlett (This used to be commit 25cadce67bc8effd4248ab993ae78e1d8511d994)

2002-01-20This is another *BIG* change...Andrew Bartlett1-42/+38
Samba now features a pluggable passdb interface, along the same lines as the one in use in the auth subsystem. In this case, only one backend may be active at a time by the 'normal' interface, and only one backend per passdb_context is permitted outside that. This pluggable interface is designed to allow any number of passdb backends to be compiled in, with the selection at runtime. The 'passdb backend' paramater has been created (and documented!) to support this. As such, configure has been modfied to allow (for example) --with-ldap and the old smbpasswd to be selected at the same time. This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua. These two backends accept 'non unix accounts', where the user does *not* exist in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to avoid conflicts in the algroitmic mapping of RIDs, they use the values specified in the 'non unix account range' paramter - in the same way as the winbind ranges are specifed. While I was at it, I cleaned up some of the code in pdb_tdb (code copied directly from smbpasswd and not really considered properly). Most of this was to do with % macro expansion on stored data. It isn't easy to get the macros into the tdb, and the first password change will 'expand' them. tdbsam needs to use a similar system to pdb_ldap in this regard. This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I don't have the test facilities for these. I plan to incoroprate at least pdb_ldap into this scheme after consultation with Jerry. Each (converted) passdb module now no longer has any 'static' variables, and only exports 1 init function outside its .c file. The non-unix-account support in this patch has been proven! It is now possible to join a win2k machine to a Samba PDC without an account in /etc/passwd! Other changes: Minor interface adjustments: pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*. pdb_update_sam_account() no longer takes the 'override' argument that was being ignored so often (every other passdb backend). Extra checks have been added in some places. Minor code changes: smbpasswd no longer attempts to initialise the passdb at startup, this is now done on first use. pdbedit has lost some of its 'machine account' logic, as this behaviour is now controlled by the passdb subsystem directly. The samr subsystem no longer calls 'local password change', but does the pdb interactions directly. This allow the ACB_ flags specifed to be transferred direct to the backend, without interference. Doco: I've updated the doco to reflect some of the changes, and removed some paramters no longer applicable to HEAD. (This used to be commit ff354c99c585068af6dc1ff35a1f109a806b326b)
2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-33/+0
This time its the pdb_getsampwuid() function - which was only being used by the SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is actually generated at login time, and the other changes here simply move that data around. This also means that (when I check some details) we will be able to use the user session key, even when we are not actually the DC, becouse its one of the components of the info3 struct returned on logon.

2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-4/+10
Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps them around for a long time - often past the next call... This adds a getpwnam_alloc and a getpwuid_alloc to the collection. These function as expected, returning a malloced structure that can be free()ed with passwd_free(&passwd). This patch also cuts down on the number of calls to getpwnam - mostly by taking advantage of the fact that the passdb interface is already case-insensiteve. With this patch most of the recursive cases have been removed (that I know of) and the problems are reduced further by not using the sys_ interface in the new code. This means that pointers to the cache won't be affected. (This is a tempoary HACK, I intend to kill the password cache entirly). The only change I'm a little worried about is the change to rpc_server/srv_samr_nt.c for private groups. In this case we are getting groups from the new group mapping DB. Do we still need to check for private groups? I've toned down the check to a case sensitve match with the new code, but we might be able to kill it entirly. I've also added a make_modifyable_passwd() function, that copies a passwd struct into the form that the old sys_getpw* code provided. As far as I can tell this is only actually used in the pass_check.c crazies, where I moved the final 'special case' for shadow passwords (out of _Get_Pwnam()). The matching case for getpwent() is dealt with already, in lib/util_getent.c Also included in here is a small change to register the [homes] share at vuid creation rather than just in one varient of the session setup. (This picks up the SPNEGO cases). The home directory is now stored on the vuid, and I am hoping this might provide a saner way to do %H substitions. TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change the remaining sys_getpwnam() callers to use getpwnam_alloc() and move Get_Pwnam to return an allocated struct.

Also set the default value of all the allocated strings to "" to avoid changing the interface (becouse pdb_get...() would point to a null string, rather than a null pointer and parts of samba rely on that). Andrew Bartlett (This used to be commit 5b4079f748e25f21162e21b439063249baf8dca6)
2002-01-15Change the passdb interface to use allocated strings.Andrew Bartlett1-50/+75
These strings are allocated using talloc(), either using its own memory context stored on the SAM_ACCOUNT or one supplied by the caller. The pdb_init_sam() and pdb_free_sam() function have been modifed so that a call to pdb_free_sam() will either clean up (remove hashes from memory) and destroy the TALLOC_CTX or just clean up depending on who supplied it. The pdb_init_sam and pdb_free_sam functions now also return an NTSTATUS, and I have modified the 3 places that actually checked these returns. The only nasty thing about this patch is the small measure needed to maintin interface compatability - strings set to NULL are actually set to "". This is becouse there are too many places in Samba that do strlen() on these strings without checking if they are NULL pointers. A supp patch will follow to set all strings to "" in pdb_default_sam(). Andrew Bartlett (This used to be commit 144345b41d39a6f68d01f62b7aee64ca0d328085)
